Rambus validates DDR4 for Arm-based data centers

Rambus validated the interoperability of its DDR4 PHY and the Arm CoreLink DMC-620 Dynamic Memory Controller, which is a fast, single-port Coherent Hub Interface (CHI) for transferring data from its CoreLink CMN-600 (Coherent Mesh Network) to the Rambus DDR4 memory PHY. Together, these IP blocks offer speeds of up to 3200 Mbps, the highest performance memory speed available on the market. Both are DFI 4.0 compliant, allowing the PHY and memory controller...

Finisar's Flextune simplifies Remote PHY deployments for MSOs

Finisar introduced a new hardware-configurable feature for wavelength-tunable optical transceivers that is designed to simplify the deployment of Remote PHY access networks constructed by Multiple System Operators (MSOs). The Finisar Flextune feature allows up to 96 wavelength-tunable optical transceivers in a Remote PHY network to self-configure their wavelengths to operate over the DWDM infrastructure without input from the host equipment nor intervention...

Quantenna samples first full-duplex 802.11ax mesh chipset

Quantenna Communications began sampling the first chipset for 802.11ax mesh repeater networks based on the newest Wi-Fi specification. The chipset combines three 4x4 802.11ax radios and integrated CPU cores for optimal mesh repeating functionality and full-duplex operation, which avoids interfering with a home gateway by using a different radio frequency. Embedded CPUs provide full Access Point (AP) and bridging functionality. “Quantenna is very...

NTT develops a cooperative WLAN with distributed smart antenna

NTT has developed a technology its calling “cooperative wireless LAN with distributed smart antenna system (D-SAS)” to improve connectivity in high-density environments such as sports stadiums. The technology consists of two key functions: one performs centralized radio resource management by taking information about the surrounding radio environment into consideration; the second optimizes parameters dynamically with the aid of the first function...
